The first depression includes a first surface, a second surface perpendicular to the first surface, a third surface perpendicular to the second surface, and a fourth surface perpendicular to the first surface and the second surface. The second depression includes a fifth surface, a sixth surface perpendicular to the fifth surface, a seventh surface perpendicular to the sixth surface, and an eighth surface perpendicular to the fifth surface and the sixth surface.

A workpiece conveying system is provided, which includes a workpiece including a workpiece main body, a cylindrical gripping part protruding from the workpiece main body, and an engaging plate attached to a tip-end surface of the gripping part, a chuck device including three jaws configured to grip the gripping part in radial directions of the gripping part, and a robot to which the chuck device is attached. The engaging plate includes an overhang part protruding from the gripping part along the tip-end surface of the gripping part, and an engaging slot, into which one of the three jaws fits, is formed in the overhang part.

A robot hand according to the present invention controls finger units by a central processing unit (CPU) based on two or more types of gripping mode tables for different purposes when a gripping object is gripped by the finger units.

There is provided a robot hand that grips and positions a work with a certain gripping force, and that rapidly conveys the work to execute assembling after gripping the work.

Prosthetic hand (1) with a wrist (13) and provided with a hand palm (2) and fingers (4) attached to the hand palm (2), wherein the hand palm (2) and fingers (4) comprise bars (5) and joints (6) connecting the bars (5) forming a construction (7) supported by the wrist (13), wherein said bars (5) occupy a position with reference to each other de-pending on an external load applied to the construction (7), wherein a reaction force for said load applied to the construction (7) is provided by or through the wrist (13), and wherein the construction (7) has an unloaded position wherein the fingers (4) are stretched and a plurality of loaded positions corresponding to loads applied to an inner side of the hand (1) wherein the construction (7) is deflected from the unloaded position wherein the fingers (4) are stretched into a series of loaded positions in which the fingers (4) are flexed into increasingly bonded positions so as to eventually close the hand (1), and that said construction (7) is provided with a locking mechanism (9) to lock the construction (7) in one of the plurality of loaded positions.

The invention relates to a robot gripper comprising: a main gripper body that has a connection flange designed to secure the rotational gripper to a tool flange of a robotic arm; also a base element that is mounted on said main gripper body such that it can rotate about a first rotational axis by means of a first rotational joint able to be adjusted automatically by a first drive motor; and a first gripper finger mounted such that it can rotate about a second rotational axis aligned parallel to the first rotational axis, relative to the base element, by means of a second rotational joint which can be adjusted automatically by a second drive motor; as well as at least one additional gripper finger, said second rotational joint being designed to adjust the first gripper finger individually, using the second drive motor, independently of said at least one additional gripper finger.

An autonomous object modeler includes a modeling table, a controllable arm, a depth camera attached to the controllable arm, and a controller to control operation of the modeling table, the controllable arm, and the depth camera. The modeling table may be movable and includes a mass sensor to produce mass sensor data indicative of a mass of an object positioned on the modeling table. The controllable arm includes a force-torque sensor to produce force-torque sensor data indicative of an inertia of the object while the object is moved by the controllable arm. The controller is configured to control operation of the controllable arm to reposition the object on the modeling table to generate three-dimensional models of the object. The three-dimensional models include the mass data and the inertia data.

An attachment apparatus according to an embodiment of the present technology includes a hand portion and a control unit. The hand portion includes a restriction portion that restricts a movement of a flat cable in a width direction and a holding portion that holds at least one of both surfaces of the flat cable. The control unit causes the flat cable to be held by a first holding force while restricting the movement in the width direction at a first position on the flat cable, causes the hand portion to move to a second position on the flat cable while maintaining the first holding force, and causes the flat cable to be held at the second position by a second holding force to attach the flat cable.

The present disclosure relates to a storage and transfer apparatus for mass transfer of a plurality of data discs to trays of a plurality stacked disc drives. The storage and transfer apparatus may store a plurality of discs with the disc hold pins retracted and the telescopic sections collapsed over each other. In such a configuration, the stored discs may lie in contact with each other. The storage and transfer apparatus may transfer the plurality of discs to the trays of the plurality of stacked disc drives with the discs holding pins extended and the telescopic sections extended relative to each other.

A robot system includes a robot, a vision sensor, and a controller. The vision sensor is configured to be detachably attached to the robot. The controller is configured to measure a reference object by using the vision sensor and calibrate a relative relationship between a sensor portion of the vision sensor and an engagement portion of the vision sensor, and teach the robot by referring to the relative relationship and by using the vision sensor, after the vision sensor is attached to the robot.
